Conclusions: In an urban primary school in Australia, head lice infestation was present at a hyperendemic level. Clustering by class indicated the classroom as a main source of infestation. Control strategies implemented in schools and including the education of teachers and parents need to be evaluated.
Head lice (Pediculus Capitis) are a common problem that most parents, students and teachers in Australia are familiar with. They are tiny parasites, about the size of a sesame seed, and live on the human scalp and hair. They feed on human blood up to 4 times a day.
About 6–12 million children between the ages of 3 and 11 are treated annually for head lice in the United States alone. High levels of louse infestations have also been reported from all over the world, including Israel, Denmark, Sweden, U.K., France, and Australia.
Head lice are a common problem, especially for kids. They spread easily from person to person, and sometimes are tough to get rid of. Their bites can make a child's scalp itchy and irritated, and scratching can lead to infection.
Head lice are found worldwide. In the United States, infestation with head lice is most common among pre-school children attending child care, elementary schoolchildren, and the household members of infested children.
Head lice infestations are common, affecting an estimated 6 million to 12 million people each year. Lice are most common among school-age children who are more likely to have close contact with each other or share combs, brushes, hats and other objects that touch the hair.
Head lice seem to be more common in Caucasian, Hispanic, and Asian American people than in African American people. For example, fewer than 0.5% of African American schoolchildren experience head lice compared with about 10% of schoolchildren of other races.
HEAD LICE SHOULD NOT CAUSE EMBARRASSMENT
They don't discriminate based on income, race, hygiene or pretty much any other factor. If you have a head of hair with a scalp underneath it, that warm, moist environment, clean or dirty, is just what they're looking for.
Head lice are annoying, but they're not dangerous and they don't spread disease. They're not a sign of poor hygiene — head lice need blood and they don't care whether it's from someone who's clean or dirty. It's best to treat head lice right away to prevent them from spreading.
Around 1 to 2 of every 100 Australians are estimated to have public lice.
In the United States, infestation with head lice is much less common among African-Americans than among persons of other races. The head louse found most frequently in the United States may have claws that are better adapted for grasping the shape and width of some types of hair but not others.
Residue from hair products. Beads of dead hair tissue on a hair shaft. Scabs, dirt or other debris. Other small insects found in the hair.
Body lice infestations (pediculosis) are spread most commonly by close person-to-person contact but are generally limited to persons who live under conditions of crowding and poor hygiene (for example, the homeless, refugees, etc.).
Diagnosis of head lice
You may see small white or brown oblong eggs ('nits') attached to the shafts, and they are difficult to move. The live lice are more difficult to find as they move rapidly away from disturbances in the hair. Adult lice are 2 to 4mm long and whitish brown in colour (see images).
Shaving the head does not cure lice. The itching should go away within a few days, but the medicated treatment will need to be repeated in 5 to 7 days to kill any new lice that may have hatched since the first treatment.
In the middle ages, humans couldn't get away from lice. They were an unavoidable part of their life and lice didn't discriminate; they infected all parts of society from serfs to royals. People in the Middle Ages took lice to their grave as well. They lived a life of itch, itch, itch!
What repels head lice? Coconut, tea tree oil, lavender, eucalyptus, rosemary, lemon grass, and peppermint are scents popularly believed to repel lice. Using any coconut scented shampoo and conditioner is an easy way to increase your defense. At 1% concentration, tea tree oil killed 100% of head lice after 30 minutes.
Heat Method:
There are recent studies that show that treatment of lice with heat can be quite effective in killing head lice. Products such as Lousebuster are very effective but even a home hairdryer can successfully treat lice.
Sorry to break it to you, but a buzz cut with clippers will definitely not get rid of lice. The reason shaving will not work is because lice live on the base of the hair, and on the scalp.
Since lice are uniquely adapted to crawl along a hair shaft, and since lice glue their eggs to the hair shaft, this often prevents African Americans from getting head lice.
Not everyone feels lice moving around on their scalp, but some people do. Dr. Garcia says that most of her patients say they “don't feel anything,” but others may get a creepy, tickling sensation as lice move around their head.
